Date Fri, 01 Jul 2016 01:49:11 GMT

     [ https://issues.apache.org/jira/browse/HBASE-14743?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Reid Chan updated HBASE-14743:
------------------------------
    Attachment: HBASE-14743.011.patch

HadoopQA didn't test last 010.patch...?

This patch change the initial value of:
"globalMemStorePercentMinRange = conf.getFloat(MEMSTORE_SIZE_MIN_RANGE_KEY, globalMemStorePercent
/ 3);" and "blockCachePercentMinRange = conf.getFloat(BLOCK_CACHE_SIZE_MIN_RANGE_KEY, blockCachePercent
/ 4);"

Thanks
